Description

Technical Field

[0001] This utility model relates to the field of SMT automation machinery technology, and in particular to an AGV wireless charging device for an SMT de-assembly and reassembly machine. Background Technology

[0002] Surface Mount Technology (SMT) is a core technology in modern electronics manufacturing and is widely used in consumer electronics, communication equipment, automotive electronics and other fields. The core equipment of SMT technology is the SMT placement machine, which can automatically pick up components and place them accurately on the PCB through an electronic eye recognition device.

[0003] Typically, when the tape in a pick-and-place machine is about to run out, an SMT splicer is needed to connect the head of a new tape reel to the tail of the old tape reel. After splicing, the new tape reel is placed at a preset station on the pick-and-place machine. The SMT splicer is usually equipped with an AGV (Automated Guided Vehicle) at the bottom. When the pick-and-place machine needs to change materials, the AGV transports the SMT splicer to each material bin of the pick-and-place machine in sequence to perform the material change. The current power supply method of the AGV mainly relies on contact charging, that is, power is transferred through physical electrode contact. This charging method requires the AGV to make physical contact with the charging equipment, and the charging process is cumbersome. In highly automated scenarios, it is necessary to frequently plug and unplug the charger and replace the battery, which affects the charging efficiency and service life. Utility Model Content

[0034] Please see Figures 1 to 4 As shown in the illustration, this application provides an AGV wireless charging device for an SMT de-assembly / reconnection machine, comprising an AGV trolley 10, a transmitter 20, and a receiver 30. The AGV trolley 10 is configured to carry the SMT de-assembly / reconnection mechanism 40 and drive it to move along a preset path. The SMT de-assembly / reconnection mechanism 40 is configured to connect the tape head of a new tray to the tape tail of an old tray in the pick-and-place machine when the tape is about to run out, and then place the new tray at a preset station on the pick-and-place machine. The transmitter 20 is laid on the ground 50 in a designated area of ​​the workshop. The transmitter 20 is electrically connected to an external power supply device, which is configured to supply power to the transmitter 20 so that the transmitter 20 generates a high-frequency magnetic field that can penetrate non-conductive media. The receiver 30 is installed at the bottom of the AGV trolley 10 and is connected to the battery of the AGV trolley 10. The receiver 30 is configured to receive the high-frequency magnetic field generated by the transmitter 20 and convert the received high-frequency magnetic field energy into DC power to charge the battery. During charging, the AGV trolley 10 moves above the transmitter 20 and charges the battery through the cooperation of the transmitter 20 and the receiver 30.

[0035] Specifically, the external power supply equipment supplies single-phase 220V AC power to the transmitter 20.

[0036] By setting up a transmitter 20 electrically connected to an external power supply on the ground 50 in a designated area of ​​the workshop, and setting up a receiver 30 connected to a battery at the bottom of the AGV trolley 10, wireless charging of the battery is achieved through the principle of resonant coupling when the AGV trolley 10 moves above the transmitter 20. This avoids the cumbersome process of frequently plugging and unplugging the battery for charging and replacing it, improves the efficiency and convenience of charging, and increases the working time utilization rate of the material receiving and unloading machine.

[0037] In one embodiment, the receiving unit 30 includes at least one first receiving coil plate 31, which has a built-in receiving coil and is detachably fixedly installed on the bottom of the AGV trolley 10; the transmitting unit 20 includes at least one transmitting coil plate 21, which has a built-in transmitting coil and is fixedly laid on the ground 50 of a designated area in the workshop.

[0038] By using coil plates in the transmitter 20 and receiver 30, and taking advantage of the simple structure of the coil plates and the adjustable characteristics of the coils, the transmitter 20 and receiver 30 are provided to meet the different requirements of wireless charging power, frequency and other parameters in different scenarios. This provides a transmitter 20 and receiver 30 with a simple structure and high flexibility.

[0039] In one embodiment, the receiving unit 30 includes a first receiving coil plate 31, and the transmitting unit 20 includes a plurality of transmitting coil plates 21, which are closely attached to the floor 50 of the workshop and electrically connected to each other.

[0040] By setting up multiple transmitting coil plates 21 tightly electrically connected, the transmitting range of the high-frequency magnetic field of the transmitting unit 20 is increased, so that the AGV trolley 10 does not need to be precisely aligned with a specific position when charging, which improves the fault tolerance of alignment and the convenience of charging.

[0041] In one embodiment, the transmitting coil board 21 is rectangular, and multiple transmitting coil boards 21 are detachably and tightly electrically connected, with the input terminals of the multiple transmitting coil boards 21 connected to the same external power supply device.

[0042] The rectangular transmitter coil plate 21 design provides a modular mounting structure for the transmitter 20. Multiple closely connected transmitter coil plates 21 can be flexibly adjusted in terms of mounting specifications according to actual needs to adapt to the charging requirements of different areas.

[0043] In one embodiment, the transmitting unit 20 includes a plurality of cables 22, and a plurality of wiring grooves 51 are provided in a designated area of ​​the workshop, with the cables 22 pre-embedded in the wiring grooves 51; the receiving unit 30 includes a fixing component and a second receiving coil plate 32, the fixing component being configured to fix the receiving coil plate to the bottom of the AGV trolley 10, and the second receiving coil plate 32 being configured to receive a high-frequency magnetic field and convert it into DC power to charge the battery.

[0044] The magnetic field generated by the transmitter 20 and the cable 22 ensures the charging effect and can be flexibly adjusted according to the movement path of the AGV trolley 10 or the layout of the workshop. The cable 22 is pre-embedded in the wiring trough 51, which effectively prevents the cable 22 from being interfered with and damaged by external factors. At the same time, it facilitates the wiring and maintenance of the cable 22 and extends the service life of the cable 22.

[0045] In one embodiment, the wiring groove 51 includes a plurality of grooves along a first direction ( Figure 3 The first groove 510 and several grooves along the second direction (in the direction of X) are set in the middle X direction. Figure 3 The second cable trough 511 is set in the Y direction. The first cable trough 510 is connected to the second cable trough 511. A single cable 22 is pre-embedded in the corresponding first cable trough 510 or second cable trough 511. The cable 22 is electrically connected at the junction of the first cable trough 510 and the second cable trough 511. Several cables 22 are electrically connected in the wiring trough 51 to form several transmitting coils.

[0046] By cooperating with the first slot 510 and the second slot 511, the cable 22 of the transmitter 20 adopts a cross wiring design to form several adjacent transmitter coils, thereby forming a larger high-frequency magnetic field region and improving the charging efficiency of the AGV trolley 10.

[0047] In one embodiment, the first direction and the second direction are at the same level and perpendicular to each other, and the spacing between adjacent first grooves 510 and adjacent second grooves 511 is the same to ensure that the cable 22 spacing is the same, thereby ensuring that the specifications of the transmitting coil are uniform.

[0048] The vertical orientation and uniform spacing of the cables 22 ensure the regularity of the cable layout of the transmitter 20, so that the transmitter coil specifications are uniform, which is conducive to generating a stable and uniform high-frequency magnetic field and improving the charging efficiency and stability of the AGV trolley 10.

[0049] In one embodiment, the fixing component includes a plurality of bolts, the second receiving coil plate 32 has a plurality of through holes 320 along the circumference, the AGV trolley 10 has a plurality of threaded holes at the bottom, and the threaded end of the bolt passes through the through hole 320 and is screwed into the threaded hole until the second receiving coil plate 32 abuts against the bottom of the AGV trolley 10.

[0050] Specifically, a first limiting surface 321 is provided on the second receiving coil plate 32 along the circumferential direction, and a through hole 320 is opened on the first limiting surface 321. A second limiting surface is provided on the bottom of the AGV trolley 10, and a threaded hole is opened on the second limiting surface. The first limiting surface 321 and the second limiting surface interfere with each other in the vertical direction.

[0051] The combination of bolts, through holes 320 and threaded holes provides a simple and easy-to-disassemble fixing structure for the second receiving coil plate 32 at the bottom of the AGV trolley 10.

[0052] In one embodiment, the designated area of ​​the workshop is the area within the workshop along the movement path of the AGV trolley 10.

[0053] By setting a designated area in the workshop as the area of ​​the AGV trolley 10's movement path, and laying the launcher 20 on the area of ​​the AGV trolley 10's movement path, not only is the area of ​​the AGV trolley 10's movement path in the workshop fully utilized, reducing additional space occupation and improving space utilization, but also ensuring that the AGV trolley 10 is charged in real time during its movement, thereby improving the charging efficiency of the AGV trolley 10.

[0054] In one embodiment, the designated area in the workshop is a pre-defined charging area within the workshop.

[0055] By setting a designated area in the workshop as a preset charging area, the transmitter 20 can be laid on the preset charging area. This not only facilitates the installation and maintenance of the transmitter 20 without affecting the operation of the AGV trolley 10, but also allows for the reasonable planning of the charging area's location according to actual needs, avoiding interference with other equipment or workflows, and improving the coordination and production efficiency of the entire production system.
