Description

Technical Field

[0001] The invention belongs to the field of welding technology, in particular to a welding tool for assembling radio frequency identification integrated circuit hardware equipment. Background Art

[0002] The hardware components of the RFID system mainly include RFID readers, RFID tags, antennas and management software. During the assembly process, these hardware components need to be correctly installed and connected to ensure the normal operation of the system. Components such as readers and antennas usually contain multiple electronic components, which need to be fixed on the circuit board by welding. In addition, in some cases, the wiring harness (such as power cord, signal cord, etc.) needs to be welded on the circuit board to ensure the firmness and reliability of the connecting wires.

[0003] The patent with announcement number CN221695693U discloses a circuit board welding device, including a support table, both ends of which are rotatably provided with transmission mechanisms; the two transmission mechanisms are connected by a conveyor belt transmission, and the conveyor belt is provided with a storage slot adapted to the circuit board; and the support table is provided with a welding suction mechanism. The patent proposes a circuit board welding device, which provides a storage slot adapted to the circuit board on the conveyor belt, and the conveyor belt is continuously moved by the transmission to convey the circuit board to the welding suction mechanism for welding. After welding is completed, the conveyor belt moves forward, and the subsequent circuit boards move forward at the same time. The processed circuit boards fall from the end of the support table to facilitate centralized collection, thereby improving welding efficiency and collection convenience.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] The welding is performed by driving multiple circuit boards to move under the welding head in sequence through a conveyor belt. Although this allows the circuit boards to be replenished under the welding head in time, and the welded circuit boards can also fall from the end of the conveyor belt into a collection box for centralized collection, but usually, workers are required to check the welding quality of the circuit boards. If the welding quality is found to be unsatisfactory, the welding process needs to be performed again. When the circuit boards are moved to the collection box in a centralized manner, the circuit boards will block each other, making it difficult for inspectors to observe the welding quality and appearance. In addition, the welded circuit boards require a certain amount of time to cool and solidify. Close contact may prolong the cooling time and affect the welding quality. If the quality inspection and cooling work are performed by stopping the operation of the conveyor belt, the normal welding of subsequent circuit boards will also be affected.

[0006] To this end, the present invention provides a welding tool for assembling a radio frequency identification integrated circuit hardware device. Summary of the invention

In addition, since the circuit boards are transferred from the chain to the placement column, the operation of the chain will not be affected by checking the circuit boards, thus ensuring that the subsequent circuit boards can be welded normally. In addition, when the circuit board slides on the placement column, the pressure plate 1 slides and squeezes the support block 1, so that the support block 1 can be extended in the same way as the pressure plate 2 squeezes the support block 2, and the end of the wire harness is supported, so that the originally hanging wire harness is lifted up without The lifting block is then driven to move and contact the surface of the placement column, and then the slider is driven to slide downward, so that the lifting block can be used to push the circuit board downward until the circuit board fits the support block 2 at the corresponding position, thereby avoiding the situation where the wiring harness of the circuit board whose welding quality does not meet the requirements is entangled with the wiring harness of other circuit boards due to the wiring harness falling.

The situation in which the circuit board is stuck on the placement column due to friction and cannot fall normally is avoided, thereby ensuring the normal placement work. Moreover, when the circuit board on the placement column needs to be removed, the lifting block can be used to move the circuit board to the upper end of the placement column, thereby making it easier to collect the circuit board.

[0040] One end of the pressure plate 1 26 is threadedly connected to the threaded rod 25, and both ends of the threaded rod 25 are rotatably set on the support plate 23. One side of the upper end surface of the support plate 23 is fixedly connected to the motor 3 27, and the output end of the motor 3 27 is fixedly connected to the upper end of the threaded rod 25.

[0041] One end of the second support block 33 is fixedly connected to the second spring 34 , and the other end of the second spring 34 is fixedly connected to the inner wall of the placement column 29 . The bottom of the placement column 29 is plugged and slidably connected to the second pressing plate 31 .

[0042] One end of the pressure plate 2 31 is threadedly connected to a threaded rod 3 32 , and both ends of the threaded rod 3 32 are rotatably set on the placement column 29 , and one side of the inner cavity of the placement column 29 is fixedly connected to a motor 4 30 , and the output end of the motor 4 30 is fixedly connected to one end of the threaded rod 3 32 .

[0043] A connecting frame 35 passes through and is fixedly connected to one side of the workbench 1, and two ends of one side of the connecting frame 35 are fixedly connected to sliding rods 48, the sliding rod 48 is slidably connected to the sliding block 40, and sliding rods 5 41 are slidably connected to the two sides of the sliding block 40, one end of the sliding rod 5 41 is fixedly connected to the lifting block 39, one side of the sliding block 40 is fixedly connected to an electric push rod 42, and the piston end of the electric push rod 42 is fixedly connected to one side of the lifting block 39.

[0044] A threaded rod 437 is threadedly connected to one side of the slider 40, and both ends of the threaded rod 437 are rotatably set on the connecting frame 35. A motor 536 is fixedly connected to one side of the upper end surface of the connecting frame 35, and the output end of the motor 536 is fixedly connected to the upper end of the threaded rod 437.

[0045] Specifically, when this embodiment is in use, it is used for the same batch of circuit boards with the same specifications, which are circular in shape and have a through hole in the middle; when the circuit board and the wiring harness are welded together, the electric push rod 2 13 drives the tray 12 to descend, so that the tray 12 is separated from the through hole in the middle of the circuit board, and because the wiring harness is embedded in the groove of the wiring board 3, after the circuit board and the wiring harness are welded together, even if the tray 12 is separated from the wiring board 3, the wiring board 3 will not fall off, and then the motor 1 5 is used to drive the sprocket 4 to rotate, so that the chain 2 can drive the wiring board 3 to move, and the circuit board moves with the chain 2, and when the edge of the circuit board is in contact with one side of the clamping plate 20, the electric push rod 3 21 is used to drive the pressing block 22 to descend to clamp the circuit board. The plate is pressed, and then the motor 2 16 is used to drive the threaded rod 17 to rotate, so that the threaded block 19 moves forward, so that the wiring harness is moved out of the groove of the wiring plate 3. When the placement column 29 is aligned with the through hole of the circuit board, the clamping block 22 loosens the circuit board, and the clamping plate 20 is reset, so that the circuit board can slide down with the placement column 29, and the motor 4 30 drives the threaded rod 32 to rotate, so that the pressure plate 2 31 moves upward. Since one side of the support block 2 33 is an inclined surface, when the pressure plate 2 31 contacts the support block 2 33, it will squeeze the support block 2 33, so that the support block 2 33 moves outward from the inside of the placement column 29 and supports the circuit board. Moreover, since the diameter of the placement column 29 is smaller than the through hole of the circuit board The diameter of the second support block 33 is also of a certain length, so it can be ensured that the circuit board can be sleeved on the placement column 29, and will not fall off the second support block 33 due to the large distance between the inner hole wall of the circuit board and the placement column 29, and then repeat the above operation. As the number of circuit boards on the placement column 29 increases, the second pressure plate 31 continues to rise to squeeze more second support blocks 33 out of the placement column 29. In addition, since there is a gap between each second support block 33, the circuit boards will not cover each other. At this time, when the staff inspects the welding quality of the circuit board again, it will not be difficult to observe the welding quality of the circuit board due to the mutual obstruction of the circuit boards, thereby improving the inspection efficiency. The circuit boards whose welding quality does not meet the requirements are found in time and welded again. During the inspection, the circuit boards are also cooled and solidified, which avoids the situation that the circuit boards are placed together just after welding, thereby extending the cooling time and affecting the welding quality. In addition, since the circuit boards are transferred from the chain 2 to the placement column 29, the operation of the chain 2 will not be affected by the inspection of the circuit boards, ensuring that the subsequent circuit boards can be welded normally. In addition, when it is necessary to remove the circuit board on the placement column 29, the pressure plate 2 31 is driven to move to the lowest position, and all the springs 2 34 are restored, so that the circuit board loses support and falls, and then the staff can take the circuit board upwards uniformly;

[0046] However, when the circuit board is placed on the supporting block 23, part of the wiring harness may sag. When the wiring harness sags, it may be entangled with the wiring harnesses on other circuit boards. When it is found that the wiring harness of the circuit board whose welding quality does not meet the requirements is entangled with the wiring harnesses of other circuit boards, the wiring harness needs to be separated before the circuit board whose welding quality does not meet the requirements can be re-welded. The whole process is more troublesome. Therefore, in order to avoid this situation, when the circuit board slides on the placement column 29, since the circuit board line also has a certain elasticity, the end of the wiring harness will also fit with the surface of the supporting plate 23. After the supporting block 23 supports the circuit board, the motor 3 27 drives the threaded rod 25 to rotate The pressing plate 1 26 slides and squeezes the supporting block 1 24, so that the supporting block 1 24 can be extended in the same way as the pressing plate 2 31 squeezes the supporting block 2 33, and the end of the wiring harness is supported, so that the originally hanging wiring harness is lifted and will not be separated from the upper surface of the supporting block 1 24, until the wiring harness and the circuit board are kept straight, and then the above operation is repeated, so that the wiring harnesses of multiple circuit boards can be supported, thereby avoiding the situation that the wiring harnesses of the circuit board whose welding quality does not meet the requirements are entangled with the wiring harnesses of other circuit boards due to the hanging of the wiring harnesses, and the entangled wiring harnesses need to be separated before the circuit board whose welding quality does not meet the requirements can be welded, which is more labor-saving and convenient;

[0047] When the circuit board slides on the placement column 29, the circuit board may be stuck on the placement column 29 due to friction and cannot fall normally, thereby affecting the normal placement work. Therefore, in order to avoid this situation, whenever a circuit board slides down, the electric push rod 42 drives the lifting block 39 to move and contact the surface of the placement column 29, and then the motor 5 36 drives the threaded rod 4 37 to rotate to make the slider 40 slide downward, and the lifting block 39 can be used to push the circuit board downward until the circuit board fits with the supporting block 2 33 at the corresponding position, thereby avoiding the situation that the circuit board is stuck on the placement column 29 due to friction and cannot fall normally, thereby ensuring the placement The work can be carried out normally, and when the circuit board on the placement column 29 needs to be removed, the lifting block 39 can be used to rise to move the circuit board to the upper end of the placement column 29, so that it is easier to collect the circuit board. In some cases, only part of the circuit boards may need to be collected to facilitate the subsequent batch processing of the circuit boards. Therefore, the position of the lifting block 39 can be controlled to divide the circuit board on the placement column 29 into two parts. When the lifting block 39 rises, only the circuit board above it will be ejected, so that the number of circuit boards taken out at one time can be controlled according to actual needs, thereby meeting different collection needs.
