Description

Technical Field

[0001] The present invention relates to the field of logistics sorting technology, and in particular to an e-commerce logistics cargo sorting platform and method based on RFID tag identification. Background Art

[0002] The RFID-based e-commerce logistics sorting platform affixes RFID electronic tags to goods and uses wireless radio frequency technology to achieve contactless, batch automatic identification. The platform consists of a conveyor system, an RFID reader array, a sorting robot arm / lever, and a central control system. When the labeled goods pass through the reader scanning area, the order, destination and other information stored in the tag are instantly read, and the system directs the sorting device to direct the goods to the corresponding channel in real time.

[0003] The patent with application number CN202420397821.2 discloses an express sorting pop-up machine, including a scanner, a first partition, a second partition and a control console. Three groups of rotating shafts are clamped on the side where the first partition and the second partition are close to each other. The outer surface of each group of rotating shafts is fixedly connected to a transmission shaft, and the outer surface of each group of transmission shafts is transmission-connected to a conveyor belt. The front of the first partition is fixedly connected to a drive motor, and the upper surface of the first partition is fixedly connected to a first support plate. By automatically scanning and identifying package information, the automation of express sorting is realized, which greatly improves the sorting efficiency.

[0004] Traditional e-commerce logistics sorting equipment mainly relies on fixed-installed RFID scanners and manual intervention to deal with cargo posture issues. Its core deficiency is that the scanning method is static and rigid. The fixed scanning position cannot follow the high-speed moving goods, resulting in an extremely short time window for the RFID tag to be exposed to the effective reading area. Especially on high-speed sorting lines, it is very easy to cause signal omission or misreading due to excessive relative movement, and the recognition accuracy is difficult to guarantee. Secondly, in the face of common cargo skew, vibration or stacking during transportation, there is a lack of integrated and automated correction mechanisms, which often require additional manual intervention or complex correction devices such as vision-guided robotic arms. This not only increases system complexity and cost, but also seriously slows down sorting efficiency.

[0005] In view of this, we propose an e-commerce logistics cargo sorting platform and method based on RFID tag recognition. Summary of the Invention

[0006] The purpose of the present invention is to provide an e-commerce logistics cargo sorting platform and method based on RFID tag identification, which drives a mechanical transmission chain of a worm, a worm wheel and a reciprocating screw through a motor, and controls the slider to drive the tag identification part to move in the same direction and speed as the cargo, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] An e-commerce logistics cargo sorting platform based on RFID tag recognition includes a pair of transport platforms and a scanning platform set between the transport platforms;

[0009] The scanning platform includes a support mechanism, a driving mechanism provided on both sides of the support mechanism, and a label recognition unit for scanning goods;

[0010] The driving mechanism includes a worm, a worm wheel meshed with the worm, a reciprocating screw rotating with the worm, a slider sleeved on the outside of the reciprocating screw, a transverse frame driven by the worm, and a clamping portion arranged above the transverse frame, and the label identification portion is fixed to the top of the slider;

[0011] The rotating worm of this setting meshes with the worm wheel, driving the reciprocating screw to rotate, and the slider drives the tag recognition unit to move left and right at the speed of the transport platform transporting the goods;

[0012] The clamping part includes a bending plate rotatably connected to the top surface of the transverse frame at the bending part, a lower protruding rod provided on the bottom surface of one end of the bending plate, and a plurality of clamping plates rotatably connected to the other end;

[0013] In this setting, when the slider moves horizontally, first move the lower protruding rod to change the inclination angle of the bending plate, and then use the clamping plate to place the goods directly under the label identification part, and then contact the horizontal moving frame to allow the clamping part to move with the goods.

[0014] In the technical solution of the present invention, the support mechanism includes a fixed frame, two conveying shafts rotatably connected between the fixed frames, a conveying roller sleeved on the outside of the conveying shaft, and a conveyor belt sleeved between the two shafts. The top surfaces of both ends of the fixed frame are provided with frame surface through grooves that pass through from top to bottom. The conveying roller on the left is rotatably connected to the inside of the fixed frame, and the conveying roller on the right is clamped and fixed to the outer wall of the conveying shaft.

[0015] In the technical solution of the present invention, the support mechanism also includes two groups of support frames fixedly connected to the top surface of the fixed frame by bolts, several sliding rods clamped and fixed between a pair of support frames, and light-shielding frames clamped and fixed to the outside of several support frames.

[0016] The above configuration provides a prerequisite for the stable operation of the driving mechanism.

[0017] In the technical solution of the present invention, the driving mechanism also includes a limit frame that provides a moving range for the slider and the transverse frame, and a motor coaxially connected to the outer end of the worm. The other end of the worm is clamped and fixed at the end position of the left transmission shaft, and the worm wheel is clamped and fixed to the outside of the reciprocating screw. The two ends of the reciprocating screw are rotatably connected to the inside of the fixed frame.

[0018] In the technical solution of the present invention, a sliding groove running through the top and bottom is provided on the top horizontal plate of the slider, the transverse moving frame is slidably connected to the inside of the limit frame and has a concave transverse cross-section, an upper protruding rod is integrally formed at the corner of the transverse moving frame, and a limit sliding groove for the movement of the slider is provided on the top surface of the limit frame.

[0019] The above setting uses an external motor to drive the worm, so that the label recognition part can move synchronously with the goods and remain relatively stationary, thereby ensuring continuous operation capabilities in high-throughput sorting scenarios.

[0020] In the technical solution of the present invention, the clamping portion also includes an arc spring connected between the bending plate and the clamping plate, one end of the arc spring is welded and fixed to the outer wall of the bending plate, and the other end is welded and fixed to the outer wall of the clamping plate.

[0021] In the technical solution of the present invention, a circular hole matching the size of the upper protruding rod is opened at the bending portion of the bending plate, and the lower protruding rod is rotatably connected to the end of the bending plate and its bottom end extends to the inside of the shifting groove.

[0022] When the tag recognition unit moves with the goods, the above arrangement avoids tag recognition failure caused by skewness or vibration of the goods through the two clamping plates.

[0023] In the technical solution of the present invention, the label identification unit includes two connecting frames, a placement frame fixedly connected between the two connecting frames by bolts, and a scanner fixedly connected to the bottom surface of the placement frame by bolts.

[0024] In the technical solution of the present invention, the connecting frame is fixedly connected to the top surface of the slider by bolts, and a plurality of regularly distributed holes that are adapted to the size of the slider are opened on the outer wall of the connecting frame.

[0025] The above arrangement fixes the connecting frame on the top surface of the slider, so that the label identification part can move synchronously with the goods, and complete the scanning of the goods information in a relatively static state.

[0026] On the other hand, the present invention also provides an e-commerce logistics cargo sorting method based on RFID tag identification, using the above-mentioned e-commerce logistics cargo sorting platform based on RFID tag identification, comprising the following steps:

[0027] S1. When the control system drives the transport platform to transport the goods to the interior of the scanning platform, the external detection unit is sensed and the motor in the control drive mechanism is started;

[0028] S2. The motor drives the worm to rotate. The rotating worm engages the worm wheel, driving the reciprocating screw to rotate, which drives the slider to move horizontally to the right inside the limit frame, thereby causing the label identification part fixed on the top of the slider to move together;

[0029] S3: The tag recognition unit moves right at the same speed as the cargo. The scanner and the RFID tag on the cargo surface are displaced a certain distance and the scanned cargo information is transmitted to the control system. The control system controls the sorting arm to push the cargo onto different sorting belts.

[0030] S4. When the scanner moves to the rightmost end, the control system increases the motor output power to quickly reset the label recognition unit;

[0031] S5. During this process, when the slider moves to the right, the lower protrusion is first moved through the slot to change the inclination angle of the bending plate, and the goods are placed directly below the label identification part through the clamping plate;

[0032] S6. Then, the slider contacts the right side wall of the transverse frame, driving the clamping part to move along with the goods to ensure the stability of the goods transportation;

[0033] S7. The slider then moves to the left, and after the clamping part is reset by the slot, the label recognition part and the clamping part return to their initial positions, preparing for the subsequent scanning of the goods sorting information.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. This e-commerce logistics cargo sorting platform and method based on RFID tag identification uses a motor to drive a mechanical transmission chain consisting of a worm, worm gear, and reciprocating screw. The control slider drives the tag identification unit to move in the same direction and speed as the cargo, allowing the scanner to continuously read RFID tags while remaining relatively stationary. This completely solves the problem of signal omission caused by high-speed cargo movement in traditional fixed scanning. At the same time, the system automatically speeds up and resets after scanning, ensuring continuous operation in high-throughput sorting scenarios and improving identification accuracy.

[0036] 2. This e-commerce logistics cargo sorting platform and method based on RFID tag recognition has a slider that triggers the clamping part to move in stages when the slider moves horizontally. Through a single power source, it simultaneously achieves cargo posture correction, scanning positioning, dynamic stable operation, and automatic reset, avoiding tag recognition failures caused by cargo skew or vibration, and reducing the need for manual intervention.

DETAILED DESCRIPTION

[0049] The following will provide a clear and complete description of the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0050] See also Figure 1-Figure 3 As shown, this embodiment provides a technical solution:

[0051] An e-commerce logistics cargo sorting platform and method based on RFID tag identification includes a pair of transport platforms 100 and a scanning platform 200 disposed between the transport platforms 100;

[0052] Specifically, the scanning platform 200 includes a supporting mechanism 210 , a driving mechanism 220 disposed on both sides of the supporting mechanism 210 , and a label recognition unit 230 for scanning goods.

[0053] Furthermore, the support mechanism 210 includes a fixed frame 211, two conveying shafts 212 rotatably connected between the fixed frames 211, a conveying roller 213 sleeved on the outside of the conveying shaft 212, and a conveyor belt 214 sleeved between the two shafts. The top surfaces of both ends of the fixed frame 211 are provided with frame surface through grooves 2110 that pass through from top to bottom. The conveying roller 213 on the left is rotatably connected to the inside of the fixed frame 211, and the conveying roller 213 on the right is clamped and fixed to the outer wall of the conveying shaft 212.

[0054] Furthermore, the support mechanism 210 also includes two groups of support frames 215 fixedly connected to the top surface of the fixed frame 211 by bolts, a number of sliding rods 216 clamped and fixed between a pair of support frames 215, and a light shielding frame 217 clamped and fixed to the outside of the several support frames 215.

[0055] Furthermore, the fixed frame 211 is used to ensure the stability of the overall structure of the support mechanism 210, and the frame surface groove 2110 provides a moving range for the structure in the driving mechanism 220. One of the two transmission shafts 212 is used to be connected to the driving system that controls the transportation platform 100 to ensure the same express transportation rate, and the other is used to be connected to the structure of the driving mechanism 220 to transmit power. The transmission roller 213 on the left is connected to the inside of the fixed frame 211 to prevent it from interfering with the transmission of power of the left transmission shaft 212. The sliding rod 216 on the support frame 215 is used to limit the moving range of the label identification part 230, and prevents the external light source from dry scanning the scanning process through the light shielding frame 217. This setting provides a prerequisite for the stable operation of the driving mechanism 220.

[0056] See also Figure 2-Figure 7 As shown, in this embodiment, the driving mechanism 220 includes a worm 221, a worm wheel 222 engaged with the worm 221, a reciprocating screw 223 rotating therewith, a slider 224 sleeved on the outside of the reciprocating screw 223, a transverse frame 225 driven by the reciprocating screw, and a clamping portion 227 arranged above the transverse frame 225. The label identification portion 230 is fixed to the top of the slider 224. The rotating worm 221 engages with the worm wheel 222 to drive the reciprocating screw 223 to rotate, and the slider 224 drives the label identification portion 230 to move horizontally left and right at the speed at which the transport platform 100 transports the goods.

[0057] Specifically, the driving mechanism 220 also includes a limit frame 226 that provides a moving range for the slider 224 and the transverse frame 225, and a motor 228 coaxially connected to the outer end of the worm 221. The other end of the worm 221 is clamped and fixed at the end position of the left transmission shaft 212, and the worm wheel 222 is clamped and fixed to the outside of the reciprocating screw 223. The two ends of the reciprocating screw 223 are rotatably connected to the inside of the fixed frame 211.

[0058] Furthermore, a sliding groove 2240 is provided on the top horizontal plate of the slider 224, and the transverse frame 225 is slidably connected to the inside of the limit frame 226 and has a concave cross-section. An upper protrusion 2250 is integrally formed at the corner of the transverse frame 225, and a limit groove 2260 is provided on the top surface of the limit frame 226 for the slider 224 to move.

[0059] Furthermore, the motor 228 drives the worm 221 to rotate, and the rotating worm 221 engages the worm wheel 222, driving the reciprocating screw 223 to rotate, thereby driving the slider 224 to move horizontally to the right inside the limit frame 226, thereby causing the label identification part 230 fixed on the top of the slider 224 to move together. When the label identification part 230 moves to the rightmost end, the control system increases the output power of the motor 228 and quickly resets the label identification part 230. This setting drives the worm 221 through the external motor 228, so that the label identification part 230 can move synchronously with the goods and remain relatively stationary, thereby ensuring continuous operation capabilities in high-throughput sorting scenarios.

[0060] See also Figure 2-Figure 8 As shown, in this embodiment, the clamping portion 227 includes a bending plate 2270 rotatably connected to the top surface of the transverse frame 225 at the bending point, a lower protruding rod 2271 arranged on the bottom surface of one end of the bending plate 2270, and a plurality of clamping plates 2272 rotatably connected to the other end. When the slider 224 moves transversely, the lower protruding rod 2271 is first moved to change the inclination angle of the bending plate 2270, and the goods are placed directly below the label identification portion 230 through the clamping plate 2272, and then contact with the transverse frame 225, so that the clamping portion 227 moves with the goods.

[0061] Specifically, the clamping portion 227 also includes an arc spring 2273 connected between the bending plate 2270 and the clamping plate 2272 , one end of the arc spring 2273 is welded and fixed to the outer wall of the bending plate 2270 , and the other end is welded and fixed to the outer wall of the clamping plate 2272 .

[0062] Furthermore, a circular hole matching the size of the upper protruding rod 2250 is opened at the bending portion of the bending plate 2270 , and the lower protruding rod 2271 is rotatably connected to the end of the bending plate 2270 and its bottom end extends to the inside of the shifting groove 2240 .

[0063] Furthermore, when the slider 224 moves to the right, the lower protrusion 2271 is first pushed through the slot 2240 to change the inclination angle of the bending plate 2270, and the goods are placed directly below the label identification part 230 through the clamping plate 2272. Then, the slider 224 contacts the right side frame wall inside the transverse frame 225, driving the clamping part 227 to move with the goods to ensure the stability of the goods transportation. This setting avoids label recognition failure caused by skewness or vibration of the goods through the two clamping plates 2272 when the label identification part 230 moves with the goods.

[0064] See also Figure 9 As shown, in this embodiment, the label identification unit 230 includes two connecting frames 231, a placement frame 232 fixedly connected between the two connecting frames 231 by bolts, and a scanner 233 fixedly connected to the bottom surface of the placement frame 232 by bolts.

[0065] Specifically, the connecting frame 231 is fixedly connected to the top surface of the slider 224 by bolts, and a plurality of regularly distributed holes that are adapted to the size of the slider 216 are opened on the outer wall of the connecting frame 231 .

[0066] Furthermore, the connecting frame 231 and the placement frame 232 are both used to ensure the stability of the scanner 233 when it is fixed, and through the circular hole 2310 and the slide bar 216, limit the movement range of the label identification part 230. This setting fixes the connecting frame 231 on the top surface of the slider 224, allowing the label identification part 230 to move synchronously with the goods, and complete the scanning of the goods information in a relatively static state.

[0067] The present invention also provides an e-commerce logistics cargo sorting method based on RFID tag identification, using the above-mentioned e-commerce logistics cargo sorting platform based on RFID tag identification, including the following steps:

[0068] S1. When the control system drives the transport platform 100 to transport the goods to the interior of the scanning platform 200, the external detection unit is sensed and the motor 228 in the control drive mechanism 220 is started;

[0069] S2. The motor 228 drives the worm 221 to rotate. The rotating worm 221 engages the worm wheel 222, driving the reciprocating screw 223 to rotate, thereby causing the slider 224 to move rightward inside the limit frame 226, thereby causing the label identification unit 230 fixed on the top of the slider 224 to move together.

[0070] S3: The tag recognition unit 230 moves rightward at the same speed as the cargo. The scanner 233 and the RFID tag on the cargo surface are displaced a certain distance and the scanned cargo information is transmitted to the control system. The control system controls the sorting arm to push the cargo onto different sorting belts.

[0071] S4. When the scanner 233 moves to the rightmost end, the control system increases the output power of the motor 228 to quickly reset the label recognition unit 230.

[0072] S5. During this process, when the slider 224 moves to the right, the lower protrusion 2271 is first moved through the shifting groove 2240, thereby changing the tilt angle of the bending plate 2270, and the goods are placed directly below the label identification unit 230 through the clamping plate 2272;

[0073] S6. Then, the slider 224 contacts the right side wall of the transverse frame 225, driving the clamping portion 227 to move along with the cargo to ensure the stability of cargo transportation.

[0074] S7. The slider 224 then moves to the left, and after the clamping portion 227 is reset through the shifting groove 2240, the label identification portion 230 and the clamping portion 227 return to their initial positions, preparing for the subsequent scanning of the goods sorting information.

These descriptions are not intended to limit the invention to the precise forms disclosed, and it is apparent that many variations and modifications are possible in light of the foregoing teachings.
